Watch: Big Sean Raps E-40's Verse From "IDFWU"

Big Sean is one of my favorite artists so of course I enjoy anything I see of his!

I was blessed to be in the room when this freestyle went down!

I love when he raps E-40's verse in the song, I had no idea how he was going to do with that but he KILLED it!

Want to know something more exciting about this?

Big Sean is going to be at our 'Real Street Fest" which is happening in two months, Aug. 10 and 11 so make sure you get your passes before it's sold out!
